Among cooling solutions to PCs, air cooling and water cooling compete on the plane of the enthusiast, as well as the professional world. Though air cooling is typical and less expensive, water cooling is viewed by many people as the better alternative to the high performance system. The question is, however, is water cooling more effective than air cooling? In the current article we shall dissect the similarities and dissimilarities between the two cooling solutions bearing in mind cool-down tendency, sound, conservation, and levels of cost in addition to the contribution of fans, and what is a sleeve bearing fan within the framework of your cooling system.

Air cooling is one of the historic and the most preferred ways of cooling PC components such as CPU and GPU within safe temperatures. Through a fan, air coolers force air to flow through a heatsink which is mounted on top of the component that is being cooled. The heatsink soaks in the heat produced by the component and lets it out into the air. This air, which contains the heat, is then ventilated outside the case by the fan to avoid overheating of the machine.
Conversely, the closed-loop system of water cooling is a circulating liquid coolant over the cooling components. The coolant eliminates the heat, then it is directed to a radiator, in which the liquid is cooled by the fans and is repeated again. High performance activities such as gaming, 3D rendering and overclocking are not best suited to air cooling due to its limited capacity to absorb and effectively get rid of heat as compared to water cooling.
In the aspect of cooling abilities, water cooling is usually better. Liquid coolants possess a very high heat capacity compared to air which is the ability to absorb and transfer heat. This gives the water cooling systems an ability to cope with more thermal loads and reduced temperatures particularly in heavy load situations such as during gaming or programs with high demands.
Most users can use air cooling but fail to cope when the thermal load is too much particularly in overclocked systems. Also air cooling systems tend to be more noisy as the fans they use have high RPM. What is a sleeve bearing fan? A sleeve bearing fan replaces the ball bearings with a sleeve, which leads to low noise characteristics, even at low speeds. The sleeve bearings of the fans, however, are prone to wear out quicker than the fans with the ball bearings, which are durable but are likely to be noisy.
It is however seen that the systems that are cooled using water, have a tendency of running at lower noise levels due to the efficient functioning of the pump and fans. The fans do not need to work hard since the coolant removes the heat that occurs to the components. Consequently, in heavy loading, water cooling may be relatively silent in comparison with air cooling.
Air cooling is far cheaper and quite simple to set up as compared to water cooling. A good-quality air cooler may be only 50 dollars, and it is not that hard to install it all you have to do is to put it on top of your CPU and connect the fan. Air cooling is the choice that can be used by users on a budget or as a novice.
Water cooling systems, in turn, are much more costly, with the cheapest AIO coolers going around $80. Depending on the components, custom loop systems may be several hundred dollars. Installation of water cooling also is more complicated especially when it comes to a custom loop; one has to build their own pumps, tubes, radiators, and reservoirs.
Air cooling requires little maintenance, you only have to clean up fans and heat sinks to maintain good airflow. Custom loops, and other sorts of water cooling, need increased maintenance. It should regularly be serviced with changes of coolant as well as checked to see there are no leaks and also checked on the pump. Nevertheless, AIO coolers usually request less maintenance, but still, they need periodical inspections.
Water cooling is usually favored by the user who intends to overclock his/her CPU or graphics card because of better heat control. Overclocking uses more heat in its components and air cooling devices might not meet the increased demand. Under sustained operations that attempt to overclock components, keeping the components cool is important as it will prevent thermal throttling and damage.
In order to get a better heat dissipation, water cooling is more adequate and suited to deal with higher thermal output of overclocking. The greatest advantage of custom liquid cooling loops, especially, is the ability to chill multiple components and to make sure that even extensively overclocking systems remain cool under strain. That is why usually enthusiasts who are serious about their hardware usage prefer using water cooling.
Conversely, air cooling can be used to deal with modest overclocking but not necessarily intense configuration. A user who is in milder overclocking will still find air cooling as a solution, however, someone who wants to achieve the most will find the water cooling to be more of the choice.
The debate over is water cooling better than air cooling ultimately depends on your needs, performance goals, and budget. Air cooling will be a good option provided that the user is after low cost and low maintenance with average workloads. It also has enough coolant particularly with the sleeve bearing fans, that run at low speeds producing less noise.
Water cooling however is more efficient with respect to cooling, produces less sound and is more efficient under heavy loads or in-case of overclocking. Nevertheless, it will be more expensive, as well as difficult to install, and requires some maintenance.
In the case that a simple solution at an affordable cost is of essence, air cooling is probably the most effective. But where performance is concerned and good cooling is essential then by far the best is water cooling, so long as you can be bothered to pay the price and put up with the necessary maintenance.
